Patent CA-2227207-C (CA)
Title: Multiwavelength laser source
Inventor: KOROTKY STEVEN KENNETH
IPC: H04B10/155
Filed: 1998-01-19
Granted: 2001-09-04
Abstract: A light source for generating many precisely spaced wavelength channels, based on the periodic modulation of light. CW light is periodically amplitude modulated and then coupled to a non-linear fiber where it undergoes additional modulation by the process of self-phase modulation or other non-linear effects. In a general embodiment of the multi-wavelength source (MWS), an optical modulator driven by a periodic electromagnetic signal imposes periodic amplitude modulation on light from a single longitudinal mode CW laser. The light is then coupled to a non-linear medium with an intensity dependent refractive index where it generates higher order spectral sidebands by the process of self-phase modulation and/or other non-linear effects. The frequency spacing between the spectral components is equal to the repetition rate of the modulation. The shape of the spectrum (i.e. the relative amplitudes of the spectral components) can be modified by adjustments to: the amplitude modulated waveform; the optical power of the waveform. when coupled to the non-linear medium; and/orcharacteristics of the non-linear medium such as the non-linear refractive index, the length and the dispersion.

Patent CA-2232587-C (CA)

Abstract: Determining in a wireless telecommunication switching system a base station on which a wireless handset is registered and using information concerning background noise at the location of the base station to automatically adjust the ringer and voice volumes for each call received by the wireless handset while registered on that base station. Further, the wireless telecommunication switching system automatically adjusts the voice volume when a call is handed off from one base station to another base station. Each base station may automatically determine the amount of background noise and transmits this information to the wireless telecommunication system controller which stores this information for future use. Also, each time a user of a wireless handset adjusts the volume of the handset, this information may be transmitted to the wireless communication switching system controller which stores the information as a preference for the user in the area served by that particular base station. In addition, the system administrator may determine the background noise for each base station and does so for different times of day. Finally, the system administrator may determine the noise level for the different areas of the building and as base stations are added to the wireless telecommunication system, they inherit the attributes of the area where they are placed.

Abstract: Cardiac output is measured utilizing a catheter in conjunction with the indicator dilution technique. Non-thermal analyte-containing fluid is used as the injectate. This fluid is biocompatible with and metabolizable within the body of the patient. An analyte concentration sensor is mounted upon the catheter and located downstream within the bloodstream from the port from which the analyte-containing fluid is expressed. Because of the matching of rapid concentration sensor response with an analyte-containing fluid which is metabolizable, the measurement of cardiac output may be carried out as often as about one to three minutes in conjunction with an infusion internal substantially less than the measurement frequency interval. The analyte-containing fluids are selected from a group consisting of ammoniacal fluid, heparin, ethanol, a carbon dioxide releasing fluid, glucose, and anesthesia agent. The system performs in conjunction with a microprocessor-driven controller which automates the measurement procedure and provides a display of cardiac output and various cardiovascular parameters.
